EEA Faceted Navigation (Plone 4.x)

Project description

Plone Faceted Navigation product

A powerful and effective way to find content in large collections


Faceted Navigation (FN) gives you a very powerful interface to improve search within large collections of items. It lets you gradually select and explore different facets (metadata) of the site content and narrow down you search dynamically.

On the contrary plone collections are static, in a way that the site admin decide the search criteria and the end user is not able to further sort or filter the presented results.

FN is fully customizable, site admin may decide that some criteria (facets) must have fixed values while other may be presented as filter options to the web visitor.

FN may very well replace the standard collection content type, since it covers same functionality and it adds a lot more features.

Main features

FN can also be used as an advanced search for your site. It comes with plenty of configuration options and features like:

  1. Easy customisable GUI via drag-n-drop, no restart needed.
  2. Facets can be set to fixed default values and hidden.
  3. Facets can be placed in standard search or extended search panels, to not intimidate novice users and have cleaner interface
  4. Facets can be displayed via several widgets like select, radio, text input, tag cloud, date range and more
  5. Expandable and collapsable widgets with many values
  6. Automatically counts number of content items beside each facet value
  7. Possibility to show or hide the options with zero results (show only the facets which return content)
  8. Ability to create your custom content types definition to be used as a combination of interface and portal type, presented in a single widget.
  9. Export of search result in RSS.
  10. Pleasant user interface based on Ajax JQuery, implemented with “deep linking”, so bookmarking a faceted query works, browser history supported.
  11. Export / Import of faceted settings as XML. Useful to replicate same facets navigation on another site.
  12. Search engine friendly, disabling javascript acts as a normal collection batch list.
  13. Synchronisation of settings across multiple languages, I18N support.
  14. High performance by caching faceted catalog queries via distributed memory object caching system: memcached


The easiest way to get eea.facetednavigation support in Plone 4 using this package is to work with installations based on zc.buildout. Other types of installations should also be possible, but might turn out to be somewhat tricky.

To get started you will simply need to add the package to your “eggs” and “zcml” sections, run buildout, restart your Plone instance and install the “eea.facetednavigation” package using the quick-installer or via the “Add-on Products” section in “Site Setup”.

You can download a sample buildout at:

Getting started

Go to the “Actions” tab on a Collection of Folder, and click “enable faceted navigation”.
